I have a Kohler neo angle shower unit with a glass panel enclosure with two doors that slide open. I also have a Moen shower head and a 6" arm that roates down at only about 35 degrees or so. This causes the water to spray right through the gaps in the glass panel enclosure. I need to find a shower head that will will rotate further down toward the ground. I don't think I can use a longer arm due the small space of the enclousre. Speakman says they make a shower head that rotates 50 degrees, but I'm not sure that's enough. Help!
